The beat the song is built on is one bar, played through bars 67-74, 107-121 and 123-138 -- 28.1% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 89 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 100 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 105 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 105, 126, 147, 169 and 190 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on crash, hi-hat, snare and kick, in 3/4 at 190 BPM, counted in thirty-second notes. It is written out above, and it covers 28.1% of the bars the kit plays.
Bars 67-74, 107-121 and 123-138. The time is kept on the hi-hat to start with, and it changes 4 times over the song.
89 out of 100 on its own -- hard. The song as a whole is 100 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
